Pothole Tyre Damage in London: Should You Repair or Replace Your Tyre?

Hitting a pothole can happen in seconds, but the damage it causes to your car can affect your safety long after the impact. A sudden bang, steering vibration, loss of tyre pressure or a visible bulge could all indicate that your tyre has been damaged.

Potholes are a familiar problem for drivers across London. Whether you are travelling through busy town centres, residential streets or main roads, an unexpected hole in the road can damage your tyres, wheels and suspension.

But how do you know whether a tyre damaged by a pothole can be repaired or needs replacing? And is it safe to continue driving after hitting one?

In this guide, FlatFix Tyre explains the warning signs to look for, what to do immediately after hitting a pothole, when a tyre repair may be possible and when you should arrange a replacement.

Can a Pothole Damage Your Car Tyres?

Yes. A pothole can damage a tyre when the wheel drops into a hole and strikes its sharp edge or the road surface underneath. The force of the impact can compress the tyre against the wheel rim, potentially damaging the rubber or its internal structure.

The severity depends on several factors, including the depth and shape of the pothole, your speed, tyre pressure, tyre condition and the size of your wheels.

Not all damage is immediately visible. A tyre may look normal from the outside but still have internal damage after a heavy impact. This is why it is important to have a tyre professionally inspected if you notice unusual symptoms.

7 Signs Your Tyre May Have Pothole Damage

After hitting a pothole, pay attention to how your car behaves. The following warning signs could indicate that your tyre or wheel needs attention.

1. A Bulge or Bubble on the Tyre Sidewall

A bulge on the sidewall is one of the most important warning signs to look for. It may appear as a raised area or bubble on the side of the tyre. This can indicate that the tyre's internal reinforcing structure has been damaged, allowing the outer rubber to push outwards.

2. Sudden Loss of Tyre Pressure

If your tyre pressure drops shortly after hitting a pothole, the impact may have caused a puncture, split or damage around the tyre bead or wheel rim.

You may notice a tyre pressure warning light, a visibly deflated tyre, your car feeling unstable, or having to inflate the same tyre repeatedly. Do not assume that adding air has solved the problem. A damaged tyre may continue losing pressure and could become unsafe.

3. A Cut, Split or Crack in the Sidewall

Inspect the visible sidewall for cuts, splits, deep abrasions or exposed cords. Pothole impacts can damage this area because the tyre is compressed against the wheel. Sidewall damage is particularly serious because the sidewall flexes continuously while the vehicle is moving.

A tyre with structural sidewall damage cannot normally be repaired safely and will generally need replacing following professional inspection.

4. Steering Wheel Vibration

If your steering wheel starts vibrating after hitting a pothole, the impact may have affected the tyre, wheel or wheel balance. Possible causes include a damaged or distorted tyre, a bent alloy wheel, a wheel balancing problem, or wheel alignment/suspension damage.

Do not ignore new vibration, particularly if it becomes stronger as your speed increases. Have the vehicle checked to identify the cause.

5. Your Car Pulls to One Side

If your vehicle starts pulling left or right after a pothole impact, the wheel alignment or suspension may have been affected. Although tyre pressure differences can also cause pulling, the problem should not automatically be treated as an alignment issue. A damaged tyre or wheel needs to be ruled out first.

6. A Cracked or Bent Alloy Wheel

The tyre is not the only component that can be damaged by a pothole. A strong impact can bend, crack or distort an alloy wheel.

Look for visible cracks around the wheel, a bent rim, air escaping around the tyre and rim, new vibration while driving, or repeated loss of tyre pressure. A damaged wheel may prevent the tyre from sealing correctly. A technician should inspect the wheel as well as the tyre before deciding what needs to be replaced.

7. Unusual Noises After Hitting a Pothole

A new knocking, clunking, scraping or humming noise after a pothole impact could indicate damage to the tyre, wheel, suspension or steering components. If the noise is accompanied by vibration, steering changes or pressure loss, stop somewhere safe and arrange an inspection rather than continuing your journey.

Can a Pothole-Damaged Tyre Be Repaired or Does It Need Replacing?

This is one of the most common questions drivers ask after hitting a pothole. The answer depends on the type, location and severity of the damage. Some minor tyre punctures may be repairable, but structural damage caused by an impact often means the tyre needs replacing. A tyre professional must inspect the tyre before deciding whether a repair is safe.

A repair cannot restore a tyre whose structural integrity has been compromised. If you are unsure whether your tyre can be repaired, arrange a professional assessment rather than taking a risk. Read more about our mobile puncture repair service in London.

Why Can't a Tyre Sidewall Be Repaired After Pothole Damage?

The sidewall is the flexible part of the tyre between the tread and the wheel rim. It flexes every time the tyre rotates and helps support the vehicle's weight.

Unlike the central tread area, the sidewall is not suitable for a normal permanent puncture repair under the relevant British repair standard. A patch or plug cannot reliably restore the strength of a structurally damaged sidewall. Continuing to use a tyre with a bulge, deep cut or other structural sidewall damage can increase the risk of sudden tyre failure.

If you notice a bulge or serious cut after hitting a pothole, avoid driving on the tyre and arrange professional assistance.

What Should You Do Immediately After Hitting a Pothole?

If you hit a pothole and suspect tyre damage, take the following steps.

1. Slow Down and Find a Safe Place to Stop: Avoid sudden braking or steering movements. If your vehicle feels unstable, or you hear an unusual noise, reduce your speed carefully and stop somewhere safe. Do not stop in a dangerous position or attempt to inspect the tyre in a live traffic lane.
2. Check for Visible Tyre Damage: Once safely parked, look at the affected tyre if it is safe to do so. Check for bulges, bubbles, cuts, splits, a visibly flat tyre, objects embedded in the tread, or damage to the wheel rim. Do not put yourself in danger next to moving traffic.
3. Check Your Tyre Pressure: If you have a safe place to do so and suitable equipment, check the tyre pressure against the vehicle manufacturer's recommended figures. A tyre that has lost pressure after an impact needs inspection; simply inflating it does not make it safe.
4. Do Not Continue Driving on a Damaged Tyre: If the tyre is flat, visibly damaged or losing pressure, do not continue driving on it. Driving on a damaged or underinflated tyre can make the damage worse and affect vehicle control.
5. Arrange a Professional Inspection: A tyre specialist can inspect the tyre and determine whether it is repairable or needs replacing. The wheel should also be checked if the impact was severe. If the car pulls to one side or makes unusual noises, arrange an inspection of the steering and suspension.

Can You Drive with a Bulge in Your Tyre After Hitting a Pothole?

No. You should not drive on a tyre with a suspected structural bulge. A bulge indicates that the internal structure of the tyre has been weakened. Although the tyre may still hold air, that does not mean it is safe.

The risk of failure can increase when the tyre becomes hot or is placed under additional load. If you notice a bulge:

• Stop in a safe location.
• Avoid driving further on the damaged tyre.
• Do not attempt to repair the bulge yourself.
• Arrange professional tyre inspection and replacement if required.

Can a Pothole Damage Your Alloy Wheel?

Yes. A pothole can damage both the tyre and the alloy wheel, especially when the wheel strikes a sharp or deep edge. A bent wheel may cause air to escape between the tyre and the rim. A cracked wheel can also affect the safety of the vehicle.

Signs of possible alloy wheel damage include a visible bend or crack, air escaping around the rim, repeated pressure loss, steering wheel vibration, or a change in the way the vehicle handles.

Replacing the tyre alone may not solve the problem if the wheel is also damaged. The wheel must be inspected before a replacement tyre is fitted.

Why Pothole Damage Is a Concern for London Drivers

London drivers encounter a wide range of road conditions, from busy main roads and junctions to residential streets and roads affected by heavy traffic. Potholes can be difficult to spot, particularly during rainfall, at night or when standing water covers the road surface.

The wider UK problem is significant. According to road safety charity TyreSafe, its analysis estimated the financial impact of pothole-related vehicle repairs at £589 million in 2025. The same analysis reported that the AA attended 613,638 pothole-related breakdowns during that year. These figures cover the UK rather than London alone, but they demonstrate why drivers should take pothole impacts seriously.

For London motorists, checking tyres after a heavy impact is a sensible precaution. Even if your vehicle appears to be driving normally, hidden damage may not be immediately obvious.

How Can You Reduce the Risk of Pothole Tyre Damage?

You cannot avoid every pothole, but a few sensible driving and maintenance habits can help reduce the risk of damage:

• Keep your tyres at the correct pressure: Follow the vehicle manufacturer's recommended figures to reduce unnecessary stress.
• Check your tyres regularly: Look for cuts, bulges, cracks, uneven wear and embedded objects, paying close attention to sidewalls.
• Keep a safe following distance: Gives you more time to identify road hazards and respond safely.
• Adjust your speed to road conditions: Reduce speed where visibility is poor or the road surface is uneven. Avoid sudden swerving that could endanger other road users.
• Avoid driving through deep water where possible: Standing water hides potholes and makes depth impossible to judge.
• Do not ignore changes in your vehicle: Check new vibration, steering problems, unusual noises or repeated tyre pressure loss promptly.
